A processing machine includes a splash guard, a tool spindle that is provided inside a processing area and holds a tool, and an automatic tool changer that is movable between an internal-side tool changing position inside the processing area and a standby position outside the processing area and changes the tool held by the tool spindle at the internal-side tool changing position. The splash guard includes a cover body that is coupled to the automatic tool changer, defines and forms the processing area when the automatic tool changer is positioned at the standby position, and enters the processing area when the automatic tool changer moves from the standby position to the internal-side tool changing position.

A tool change unit includes a base and two tool arms rotatably mounted on the base and respectively located on two sides of the base. Each arm body includes a position-returning element, a gripping element, and an actuation element. The position-returning element enables the tool arm to rotate for upward and downward moving between a first position and a second position. The gripping element functions to grip a main-axle tool or a magazine tool. The tool change unit is combinable with a power unit to form a tool change device. The power unit drives the tool change unit to do rotation or rotation and upward and downward movement.

A machine tool includes a turret including first and second stations, a tool storage unit capable of storing tools therein, a machining control unit for controlling a tool in accordance with a machining program, a tool changing unit for replacing the tool attached to the turret with a tool stored in the tool storage unit, and a tool pattern memory for memorizing, as a first tool pattern, a combination of tools at the first and second stations which is associated with a first part of the machining program and, as a second tool pattern, a combination of tools at the first and second stations which is associated with a second part of the machining program after the first part. When machining is stopped during execution of the second part, the tool changing unit changes tools in accordance with a past tool pattern saved in association with a part before stop on the machining program.

Disclosed is a gripping system for receiving a processing tool, and to a storage system. These processing tools are used in processing machines or centres in the woodworking industry. Also disclosed is a processing machine with the above-mentioned storage system. This processing machine is used for processing elongate pieces of wood.

Tool magazine for the provision of tools for a machine tool, wherein the tool magazine has a multiplicity of receiving positions for tools. A first tool can be removed from or inserted into a first receiving position along a removal direction, and at least one further receiving position for receiving a further tool is provided.

A machining system for workpiece machining includes a machining cell, to which a workpiece holder for fixing a workpiece, a machining head for machining the workpiece and a robot for workpiece cleaning are assigned, wherein the robot has an articulated robot arm which is mounted with an initial section on a machine frame connected to the machining cell and which is provided at an end section remote from the initial section with a nozzle, which is designed to provide a jet of compressed air, a joint being arranged between the initial section and the end section, wherein the joint is provided with a pneumatic drive for providing a relative movement between the initial section and the end section.

A tool storage includes a tool receiver, a tool magazine, and a tool carriage. The tool receiver is provided on a one side of a machine tool with respect to a workpiece holder of the machine tool along a machine tool direction and is configured to receive a tool from an outside of the machine tool. The tool magazine is provided on another side opposite to the one side with respect to the workpiece holder along the machine tool direction. The tool carriage is configured to carry the tool between the tool receiver and the tool magazine.

A blade mounting and dismounting jig is provided for mounting a blade on and dismounting a blade from a flange of a cutting apparatus which includes a boss, a blade mount for mounting the blade fitted thereover, the flange having an annular end face for supporting the blade thereon and being fixed to a distal end of a spindle, and a holder that cooperates with the flange in gripping and securing the blade in position. The blade mounting and dismounting jig includes a cylindrical jig body, a grip coupled to the jig body and having a diameter larger than the jig body, a plurality of first air ejection ports defined in a distal end portion of the jig body, a plurality of second air ejection ports defined in the jig body at a juncture between the jig body and the grip.

A change device for changing or exchanging of tools and/or workpieces. The change device has a gripper device with at least one gripper arm that extends away from a rotation support body that is rotatably supported about the rotation axis and that has a holder for respectively one tool or one workpiece at its free end. By means of a rotary power train with a rotary drive motor and a rotary drive transmission, the gripper device can be rotated about the rotation axis. Particularly the rotary drive transmission has a belt gear. A first rotary position sensor is directly or indirectly coupled with the rotation support body and/or transmission output of the rotary drive transmission without interconnection of the rotary drive transmission for detection of the rotary position of the gripper device about the rotation axis.

A tool change unit includes a base and two tool arms rotatably mounted on the base and respectively located on two sides of the base. Each arm body includes a position-returning element, a gripping element, and an actuation element. The position-returning element enables the tool arm to rotate for upward and downward moving between a first position and a second position. The gripping element functions to grip a main-axle tool or a magazine tool. The tool change unit is combinable with a power unit to form a tool change device. The power unit drives the tool change unit to do rotation or rotation and upward and downward movement.
